Temperature Sensor
A temperature sensor at the bottom of the hy-
draulic tank has a resistance between 700 and 2000
Ω, depending on the hydraulic oil temperature. The
controller reacts to the temperature signal as fol-
lows:
• When oil temperature is below −5°C (23°F),
the controller displays the fault code h-cold.
• When oil temperature exceeds 90°C (194°F),
the controller displays the fault code h-hot.
Activates Low Temperature Protection:
• The controller reduces maximum engine
speed through a CAN bus message.
Activates High Temperature Protection (optional):
• The controller reduces vehicle speed through
a CAN bus message.
Pressure Sensor
A pressure sensor in the main valve provides a sig-
nal to the hydraulic controller as an input for the
optional features: Dynamic Control, Loaded Speed
Reduction, and Load Moment Interrupt.
DIGITAL INPUTS
Switches
Two auxiliary functions can be activated by manual
switches (digital inputs): Aux2 and Aux3.
Depending on the position of the switch, the con-
troller sends a 24 volt signal to the relevant sole-
noid valve.
Interrupts
Interrupts disable the lifting/lowering and/or tilt
functions under specific circumstances. These cir-
cumstances are set by switches to interrupt an ex-
isting signal, or by the operator who activates a
switch which sends a signal to the controller.
Some of the following interrupt functions can be
configured in the Hydraulic User Interface program
from the Truck Configuration Screen:
Operator Presence System (OPS)
The OPS has an electrical switch in the seat which
sends a signal to disable the hydraulic lift, lower,
and tilt functions 1 second after the OPS switch
has been activated. In order to reset the OPS and
re-enable the hydraulic functions, the operator has
to sit on the seat again.
Lift Interrupt (ECH)
The Lift Interrupt function disables the lift and
backward tilt functions during locking and unlock-
ing of the twist locks (ECH-version).
Lift Interrupt Disabled
This function disables the Lift/Height Interrupt
function and can be set on the Truck Configuration
screen.
NOTE:
This function is NOT related to the Lift In-
terrupt Disable button on the Twist Module for CH
trucks. On CH trucks this button provides a forced
seated signal that allows repositioning of the at-
tachment on the container.
Lowering Interrupt (ECH)
This function disables the lowering function when
there is a risk that lift chains may become slack.
The lowering interrupt can be disabled by pushing
the override button on the container handler con-
trol box.
Height Interrupt (Optional)
A proximity switch disables the lift function when a
certain mast height position has been reached. The
input signal connects to the same controller pin as
for the Lift Interrupt function, but the setting of
this input in the controller is made through the
Truck Configuration screen under Height Inter-
rupt.
